Conveyor control

From PlcWiki

Revision as of 15:29, 11 January 2011

In case of defined situations (e.g. a sequence error or a not-finished product) the request for stop of a conveyor of a production line is sent to the conveyor controller. It is a software module, which is running on a computer connected to a conveyor PLC with a serial line or via Ethernet network.

The conveyor can be stopped in these cases:

1. Sequence error
2. Not-completed product and the next one is scanned
3. NOK result of any operation (setable for each operation separately)
4. Timeout for a product on a workstation expired (the product was not finished on a station within the time limit). The settings for a timeout timer is described here: Timeout timer
5. Timeout for an inactivity on workstation expired (no action taken on a station within the time limit while the product was not finished)
